What is a Converged Network Message Store (CNMS)?

VoLTE Mobile Infrastructure Converged Network Message Store (CNMS)

A Converged Network Message Store (CNMS) provides highly scalable device and service agnostic access plus elastic cloud storage of voicemail, text and video messages. A CNMS allows communications service providers and network operators to deliver a common repository for back-up and restoring end user devices, regardless of their operating system or manufacturer.

What is a Session Border Controller (SBC)?

SBC (Session Border Controller) IMS (IP Multimedia Subsystem) VoLTE Mobile Infrastructure

A Session Border Controller (SBC) is a network function which secures voice over IP (VoIP) infrastructures while providing interworking between incompatible signaling messages and media flows (sessions) from end devices or application servers. SBCs are employed in Enterprise infrastructures or any carrier network delivering commercial residential, business, fixed-line or mobile VoIP services. They are typically deployed at both the network edge and at carrier interconnects, the demarcation points (borders) between their users and other service providers.

What is the IP Multimedia Subsystem (IMS)?

IMS (IP Multimedia Subsystem) Clearwater Core VoLTE Mobile Infrastructure

The IP Multimedia Subsystem (IMS) is a reference architecture defined by the 3rd Generation Partnership Project (3GPP) for delivering communication services built on the Internet Protocol (IP). Along with providing a framework for evolving from classic circuit switch (CS) to packet switch (PS) telephony, IMS is lauded for its openness and well defined hierarchical structure.

What is Voice over Wi-Fi (VoWiFi)?

IMS (IP Multimedia Subsystem) VoLTE Mobile Infrastructure Voice over Wi-Fi (VoWiFi) Rhino TAS

Voice over Wi-Fi (VoWiFi) is a term typically employed to describe the delivery of commercial telephony services using Voice over IP (VoIP) technologies from mobile devices connected across Wi-Fi. This is typically counter to alternatives, predominantly Voice over LTE (VoLTE), in which a mobile network operator’s (MNO’s) licensed spectrum (i.e. 4G LTE) is used to carry packetized voice. Broadly speaking, VoWiFi terminology is assigned to all core IMS services accessed from unlicensed spectrum and across untrusted access infrastructures, such as public Wi-Fi access points. VoWiFi is used synonymously to describe the GSMAs permanent reference document IR.51: IMS Profile for Voice, Video and SMS over untrusted Wi-Fi access.

What is Voice over LTE (VoLTE)?

IMS (IP Multimedia Subsystem) VoLTE Mobile Infrastructure Rhino TAS

Outlined in GSMA standards, Voice over Long Term Evolution (Voice over LTE or VoLTE) is the practice of packetizing voice over the Internet Protocol (VoIP) and transporting both the signaling and media components over a 4G LTE packet switched (PS) data path. This is in contrast to delivering voice using circuit switch (CS) methodologies, which requires 4G handsets to employ a secondary 3G radio and network operators to continue supporting this inefficient access infrastructure and licensed spectrum.

The steps to VoLTE and VoWiFi

VoLTE Mobile Infrastructure Voice over Wi-Fi (VoWiFi)

Although the benefits of Voice over Wi-Fi are well known, making the first step towards the widescale deployment of packet voice technologies has proven to be problematic. Complexity, feature parity and cost have all diminished the fervor around early propositoons and now the reality of also requiring VoWiFi for offoad and coverage purposes is further stifling progress. Only Metaswitch has the complete solution.

Simplified VoLTE Roaming - From Dream to Reality

White papers VoLTE Mobile Infrastructure

Voice over LTE (VoLTE) is one of the most significant evolutions to have hit the voice world in many years, finally migrating one of the last bastions of traditional circuit switched calling to an IP based service. The migration is not without its issues however, requiring the deployment of a potentially complex infrastructure in the mobile network (known as IP Multimedia System or IMS) together with the skills enhancements required among the technical staff in those networks.

This joint white paper from BT and Metaswitch looks at some of the technical reasons for the delays in deploying VoLTE roaming, and addresses some core issues about complexity and how this can be simplified to smooth the path to full global VoLTE deployment and interconnectivity.

The Internet of Talk - The Future of Voice Communications

White papers mobile applications Mobile Infrastructure IoTalk

Telephony is the lifeblood of the telecom industry. But that blood has been getting thinner in recent years, as alternative modes of communication, as well as Internet-based providers of basic calling-type services, have grown at the expense of ordinary phone minutes.

And while mobile telephony has extended communications to billions around the world, it has recently faced an
additional challenge. The arrival of 4G and all-IP connectivity has prompted a replacement of legacy circuit-telephony infrastructure with VoIP, and specifically VoLTE. This has been a complex transition and is still ongoing.

But simply replacing old phone networks with newer IP based ones is not enough.

Integration of IoT and Communications - Disruptive Analysis

White papers mobile applications Mobile Infrastructure Internet of Things (IoT)

This paper by Dean Bubley, the founder of Disruptive Analysis, explores emerging intersections between IoT and real-time communications. It frames and segments the use cases, and examines the opportunity for telecom-type services, especially where enabled by NFV and cloud-based IoT services platforms. The reduced cost and greater flexibility of such platforms may transform telcos’ M2M business units, and enable the emergence of other service providers focused on IoT. We may see new MVNO and PaaS players emerge, taking advantage of more flexible infrastructure. IMS may itself move beyond its SIP roots, to embrace a wider diversity of IP “sessions” and M2M messaging functionality.
